FLYING-MACHINE COVER.

Application filed March 31, 1921.

T0 aZZ w ham it may concern:

Be it known that I, GLAUDIUS DORNIER, a citizen of Germany, residing atF riedrichshafen, Germany, have invented certain new and usefulImprovements in Flying-Machine Covers (for which I have filed anapplication in Germany on December 1, 1919), of which the following is aspecification.

My invention relates to flying machines and more especially to aprotection for the supporting surfaces of such machines, having for itsobject to protect in particular the covering thereof against theinfluence of the weather. To this end, there are arranged to either sideof the hull readily detachable protective coverings, capable of beingrolled up, and which suitably shaped and dimensioned will reliablyprotect the supporting surfaces toa greater or less extent against theaction of the weather. Preferably the said covering which may consist ofwaterproof canvas or the like is provided at various points withfastenings.

In the drawings afiixed to this specification and forming part thereof aflying machine embodying my invention is illustrated by way of example.In the drawing Fig. 1 is a front View and Fig. 2 a plan view.

Referring to the drawing to the right and left of the hull 1 there isarranged above each of the two supporting surfaces 2 a rolled-upcovering 3, which when unrolled and spread out assumes the position 3The two coverings are joined at their ends, and

this at the underside in the centre of the machine, by means of eyes 4and cards 5. A strip 6 of the supporting surface may be trod on in orderto facilitate the rolling up and unrolling, respectively, of thecovering. At 7 there are arranged small studs on which the covering maybe hooked by means of eyes.

In certain cases it may prove fully sufiicient to only cover the uppersurface and to attach the two coverings, which extend somewhat beyondthe ends of the wings, by means of cords or eyes relatively to thesupporting surface or some other portion of the machine.

I claim:

1. In a flying machine in combination, a pair of supporting surfaces anda pair of covers, adapted to be rolled up, attached with one end to thesupporting surface bases.

2. In a flying machine in combination. a pair of supporting surfaces,adapted to be trod on and a pair of covers, adapted to be rolled up,attached. with one end to the supporting surface bases.

3.. In a flying machine in combination, a pair of supporting surfaces, apair of covers, adapted to be rolled up, attached with one end to thesupporting surface bases and means for fastening said coverings to saidsurfaces.

In testimony whereof I aflix my signature.

CLAUDIUS DORNIER.
